Vin Diesel posted the news on Facebook with a photo of himself and Walker, saying it was "the last scene we filmed together."
Walker, 40, and his friend, 38-year-old Roger Rodas, were killed in a fiery car accident in Valencia on Nov. 30. The 2005 Porsche Carrera GT they were in slammed into a light pole and tree, and then burst into flames.
Shooting on the film was about halfway finished at the time of the crash. Universal Pictures says Walker will still appear in the movie, but it's unclear how the studio will handle the unfinished performance.
The franchise has been one of Universal's most lucrative, grossing almost $2.4 billion worldwide since 2001. The last film, "Fast & Furious 6," made $789 million.
